HP Laserjet M775 Paper Jam

[brokeprinter1]

HP Laserjet M775: Paper is jamming with errors 13.B9.D4, 13.B4.FF, 13.B2.FF and/or 13.FF.FF. Sometimes the paper will make it half way through the fuser and stop but most of the time it will reach the bottom of the fuser, bend forward between the bottom of the fuser and the metal support bracket and stick half way out before stopping. We clear the jam but it just repeats with same errors. Staples tech has worked on it 8.5 hrs so far, most of that time spent on the phone with HP support. So far they have replaced the following: HP CLJ M775 FUSER ASSY, HP LJ M775 TRAY 2 FEED ROLLER KIT, HP LJ M725 M750 M775 PAPER P/U /SEP/FEE..., HP LJ M775 SECONDARY TRANSFER ROLLER, HP LJ M775 LOW VOLTAGE POWER SUPPLY, HP LJ M775 FUSER MOTOR M4, and HP CLJ M775 DC CONTROLLER. None of this made any difference. I cannot afford to let them work on it any more. I have run all motor and sensor tests with no reported issues there. Same problem regardless of which paper tray is printed from. Any suggestions are greatly appreciated.

I would suggest it is one of the following:

Fuser guide plate.

The more common problem we have had is a registration sensor failure Part number: RM1-7922-000CN

Repairatrooper. I removed the fuser to look at the fuser guide plate and what do you know, there wasn't one! I took one off another printer we have of that model and put it on and that fixed the problem. That guide does not look like anything that can just fall off by itself so I have no clue what happened to it but that sure fixed it. Thank you so much.

RC2-6551-000CN is the fuser guide plate number.
